Although interrupt sharing is allowed for PCI devices, some
devices do not function well when they share an interrupt with
a dissimilar PCI device. Try changing the IRQ assigned to the
Ethernet controller or the other device. For example, for
NetWare Versions 3 and 4 it is recommended that disk
controllers not share interrupts with LAN controllers.
